Patent number: 12285804Abstract: A method for producing an additively manufactured, graded composite transition joint (AM-GCTJ) includes preparing a grating or lattice pattern from a first alloy A; the grating or lattice pattern includes pores in the grating or lattice patterns. The grating pattern is built from a first end to a second end being denser on the first end than on second end, and gradually reduces density by increasing the pore size and/or reducing density of the grating or lattice pattern; adding a second alloy B powder to the second end of grating or lattice pattern. The second alloy B powder is filled towards the first end. A composite is formed of first alloy A and second alloy B powder in the AM-GCTJ. The composite is subjected to hot isostatic pressing (HIP) to densify the composite. The second alloy B is graduated from the first end to the second end O of AM-GCTJ.Type: GrantFiled: June 4, 2021Date of Patent: April 29, 2025Assignees: GE Infrastructure Technology LLC, UT Battelle, LLC, West Virginia University Board of Governors on Behalf of West Virginia University, Carpenter Technology CorporationInventors: Xingbo Liu, Zhili Feng, Yanli Wang, David Novotnak, Haiyang Qian
